Learned it by ear, but it's 100% correct. You can either play it as a bar chord or with 
capo on the first fret. Very repeatitive, but worth it if you love the song. Enjoi. =D

       Bb
I'm in trouble
I'm an addict
I'm addicted to this girl
            Eb
She's got my heart tied in a knot
And my stomach in a whirl
          Bb
But even worst
I can't stop calling her
She's all I want and more
        Eb (hold)
I mean Damn
              F (if played with capo, E)(hold)
What's not to adore

             Bb
I've been playing to much guitar
I've been listening to jazz
     Eb
I called so many times
I swear she's going mad
          Bb
And that cellular-er
Will be the death of us
     Eb  (hold)    F/E (hold)
I swear, I swear
    Bb
And oh, oh, oh, oh, oh, oh, oh
Eb
oooh, oooh, oooh, oooh

                               Bb
I'm running my mouth just like I've got her
              Eb         F/E
But I surely don't
               Bb
Because she's so-o-o-o-o-o-o
Eb
Rock and Roll
               Bb
And out of my league
              Eb (hold)
Is she out of my league?
        F/E (hold)
Let's hope not.
A# (listen to the song to hear the beat)


       Bb
I'm in trouble
I'm so cliché
See that word just wears me out
          Eb
Makes me feel just like another boy
To laugh and joke about
          Bb
But even worse I can't stop calling her
I love to hear that voice
      Eb (hold)                     F/E (hold)
And honestly, I'm left with no choice


             Bb
I've been playing to much guitar
I've been listening to jazz
     Eb
I called so many times
I swear she's going mad
          Bb
And that cellular-er
Will be the death of us
     Eb  (hold)    F/E (hold)
I swear, I swear
    Bb
And oh, oh, oh, oh, oh, oh, oh
Eb
oooh, oooh, oooh, oooh

                               Bb
I'm running my mouth just like I've got her
              Eb         F/E
But I surely don't
               Bb
Because she's so-o-o-o-o-o-o
Eb
Rock and Roll
               Bb
And out of my league
              Eb (hold)
Is she out of my league?
        F/E (hold)
Let's hope not.

Bb (abrutly)

And oh, oh, oh, oh, oh, oh, oh ,oh
